Patented Apr. 19, 1938 PATENT OFFICE l A 2,114,293 MACHINE FOR MAKING MANIFOLD FORMS George L. Fulk, San Francisco, Calif., assignor to Carbon Interleaved Forms Corporation, Norwalk, Ohio, a corporation of Ohio Application November 14, 1936, Serial No. 110,876

10 Claims.

This invention relates to a method and apparatus for making manifold forms, in which onetimelcarbons are employed for making a record, and inwhich the carbons may be quickly removed from their position in the pack at the completion of the record. I

The present invention is an improvement over that shown by my copending application, Serial No. 63,282, filed Februray 10th, 1936. Manifold packs of the type with which this invention is concerned usually have three or more record sheets interleaved with the transfer strips to Aform a single unit, and frequently a large number of units are fastened together in superimposed relationship to form a pack.

Other objects of the invention will become more apparent from the following description, reference being had to the accompanying drawings, in which I illustrate a preferred embodiment of the invention. The'essential features of the invention will be set forth in the claims.

Referring now to the drawings, Fig. 1 is a. side elevation of a machine embodyingmy invention; Fig. 2 is a top plan view of the machine; Fig. 3 is a side elevation partially in section of a portion of the machine, but shown on a much larger scale than Fig. 1; Fig. 4 is a section taken on the lines 4-4 of Fig. 3; Fig. 5 is a diagram illustrating the relationship of certain rolls of the web-feeding mechanism to the web; Fig. 6 is a view illustrating the manner in which the superimposed recordvand transfer stripsy are assembled; Fig. 7 is a View of the unit after it has been separated from the assembled strips.

The manifold pack with which the present invention is particularly concerned may include any number of record strips, such as, for example, those indicated in Fig. 6, at I0, I I, I2, and I3, interposed with. suitable transfer strips I4, I5 and I6'. The record and transfer strips are fastened together, preferably with an adhesive along one edge above the perforation line I1, while the lower edges' I8 of -the transfer strip terminate above the` bottom edges of the record strip. This arrangement enables the operator to graspthe portion 20 above the perforated line, with the thumb and for'enger of one hand, and

the c /erhanging portion beneath the lowermost f edges ofthe transfer sheet with the thumb and forenger of the other hand. The two portions are then snapped apart, thus leaving the detached record strips of the unit in one hand and the' detached transfer strips of the unit in the other hand. The transfer strips are then discarded and the record strips are filed for future use.

To make the pack 2l illustrated in Fig. '1, I take rolls 30 of webs W with the desired forms printed thereon, and I provide each web with a series of openings 22 along one longitudinal edge thereof. I utilize these openings for receiving projections on feeding rolls to hold the strips in lregistration during assembling operation. 'I'he record strip rolls are indicated in Figs. 1 and 3 at 30 and'are freely movable on a support, such as a bar 3I. These bars are shown as extending laterally from a frame 32, and correspond in number to the number of record sheets required to form the desired pack.

The webs or strips W are fed from their respective rolls v3l) upwardly by a pair of feeding rollers 33 and 34, hereinafter to be more fully described. From their respective feed rbllers each web passes upwardly around respective guide bars 31 and38, after which it passes over a drum 40. Each drum is drivingly secured to a shaft 42 journalled in the frame 32, and carries a series of radially extending pins 4I which project into the web openings 22 to align the longitudinal edges of each web, as well as to align the printed form on one web with the printed forms on the other web.

Suitable rolls 45 'provided with recesses for receiving the pins 4I of the drums 40 are positioned above the respective drums, and coact therewith to retain the webs in position. Each roll 45 is journalled at the free end of an arm 41, which is pivotally mounted on the frame asA at 48 and preferably arranged to permit adjustment of the position relative to its respective drum 40.

The transfer strip is inserted between the record strips and to this end I have shown transier strips 50 in roll form, journalled on suitable shafts 5I, carriedr by the frame 32./ The web from each transfer roll lextends downwardly, forming a loop 52 within'whichl a weight 53 is cradled, thence upwardly over the guide bar 54, thence around the guides 38 of the associated record strip where it passes between adjacent webs of record strips and over the respective drums 40. f A

The transfer strips and record strips are connected together preferably by an adhesive matelco rial. This adhesive may be applied by paste rollers 60 which are journalled within paste containers 6|, carried by the frame 32. Each paste roller has two contacting surfaces, one of which forms the adhesive line 58 (Fig. 6) by means of .which adjacent record strips are fastened together, the other of which formsa line 59 (Fig. 6) by means of which the back'of each transfer strip is fastened to the back of the superimposed record strip. The upper edge of the record strip terminates between the adhesive lines 58 and 59, while the adhesive line 58 is below the line of perforation 22.

After the record strips and the interposed transfer strips have been completely assembled and secured together as above described, the portions of the record strip carrying the aligned openings 22 which are utilized for maintaining the webs in accurate alignment and registration are removed by a shearing operation. This shearing operation may be performed, as-indicated by a rotary cutter 10 driven by the motor 35 as shown in Fig. 2. After the portion of the record strip carrying the aligned openings 22 has been cut off,l

as just described, the assembled web, composed of record strips, and interposed transfer strips, is cut to form individual packs each of which comprises a plurality of secured sheets. These packs are from the assembled web by a cutter (not shown), which is adapted to be reciprocated vertically within the guide 1| by an eccentric 12 which is rigid with a shaft 13. This eccentric is connected by a rod 14 to the carrier, on which the cutter is mounted. The cutter is positioned adjacent the table 18 on each side of which an eccentrically operated rod 14 isdisposed and beneath which the shaft 13 is journalled. The shaft, in turn, is operated in timed relationship to the assembling mechanism by suitable gearing from the motor 35. If desired, however, a rotary shearing mechanism may be used, such as shown and illustrated in my copending application, Serial No. 99,104, filed Sept. 2, 1936;

The present invention is particularly concerned with a web feeding mechanism interposed between the drum 40, and each roll of paper 30. 'Ihis feeding mechanism is arranged to feed the Webs from the rolls to the respective drums 40, in such a manner as to cause the openings 22 to alignwith, or fall on the pins 4|. This prevents the tearing of the paper web and at the same time facilitates the starting up of the press, by enabling the press to be brought up to its normal or maximum speed with rapidity, without danger of breaking the web. This mechanism includes the feeding rolls 33 and 34, heretofore mentioned.

As shown in Figs. 3 and 5, each web W passes `upwardly from its respective roll 30, over and around its feed roll 34, thence downwardly around its feed roll 33, thence upwardly around guide rolls 31 and 38, to its respective drum 40. It will be noted that the rolls 33 and 34lare spaced apart and do not actually grip the paper between them.

However, the arrangement is such that these rolls frictionally engage the paper over a large portion of their periphery. These rolls are positively driven and their peripheral speed is slightly in excess ofj the peripheral speed of the drum 40. g.

paper to fall on the pins V4| of their respective drums 40.

By driving therolls 33 and 34, the feeding action of the pins 4| is limited to that required to take up the web slack between the drum and the feed roll 33, and maintain the frictional contact of the web with the rolls 33 and 34, such frictional contact being sufficiently great to withdraw the paper from the roll 30. In addition the friction between these rolls 'is suflicient to enable the machine to be started up at a comparatively high rate of speed, initiating the movement of the rolls 30 and withdrawing the webs W, Without placing any strain on theline of perforations, thereby insuring exact registration of the web.

As heretofore mentioned, the drum 4D normally maintains the web in frictional Contact with the feed rolls. As the feed rolls are positively driven at a rate of peripheral speed which is greater than the peripheral speed of the drum 40, they tend to slacken the web between the drumgand such rolls. There is, however, a drag on each roll 30 of web material, in the form of a Weight 55 which is supported by an arm 56 pivoted to the frame 32 at 51 a'nd which is positioned to ride on the periphery of its respective roll 30. Due to this drag any tendency of the feed rolls to slaken or relieve the tension on the web decreases the contact pressure between the feed rolls and the web, thereby permitting the surface of the rolls to slip relative to the web and retard the feeding of the web. This slippage prevents the accumulation of web slack between the feed rolls and the drum 40. u

The rolls 33 and 34 are driven by the motor 35 which also drives the drums 40. As shown in the drawings, especially in Figs. 1 and 3, the motor 35 is connected by a driving chain or beflt 8U, with a line shaft 8|, to which is secured a series of worm gears 82, which mesh with respective worm wheels 83, secur d to the shafts 42 of respective rolls 40. Also drivingly secured to each roll shaft 42 is a gear 84, which through the medium of idler gears 85 drive respective pinions 86, carried by the rolls 34. Secured to each roll 34 is a pinion 81, which meshes with a corresponding pinion 88, on the coacting roll 33, thus driving both rolls in synchronism with each other and slightly in excess of the peripheral speed of the roll 40.

The driving relationship between the rolls 344 and 33 and the diameters of such rolls are such that the peripheral speed of the rolls 33 and 34 is slightly in excess of the peripheral speed of the drums 40. This ratio of the peripheral speeds, by way of illustratiomis thirty four and one sixteenth inches per minute to thirty four inches per minute. y

From the foregoing description it will be apparent that I have provided an apparatus, by means of which multiple sheet forms may be expediently assembled by using webs of form material with webs of transfer material, securing the various webs together, assembling the webs of the pack without interrupting the progress of the material at any stage of the operation, and I have so arranged the web feeding mechanism as to insure utmost accuracy in the registration of the recordsheets, as well as to maintain accurate width of the pack and the various records of the individual packs.
